Will this convert from a lenovo thinkpad t420 to the t440s?

Exact same upgrade that I had and the adapter worked fine. I had a coworker that received a defective unit so if yours doesn't work then that may be the case.

It worked from my T410 to T440P, so I would think you would be ok going from T420 to T440

I think it's the same round connector as the T400 & T410 so since its working perfect on my old T400 power supply to a T440, I'd say yes.
7963
Yes. I've had it for about 3 months and it works like a charm. Use it as my primary power. Use the factory provided power as travel.

Yes. If your T60p has been modified it may accept the same memory as the T400 think pad.

I don't know about that model in particular, but I can say that the BIOS for the Lenovo Thinkpad T61 does not recognize this Startech.com ECUSB3S254F USB 3.0 card - which means no possibility of booting, but no problem for mounting devices after booting linux (for example) from another device.

this try/caddy is for ThinkPad T420i T510 W510,and T520 this as indicated in the specs.

I use it with a t440p and docking station as well as a Levovo Helix USB port replicator.

I'm afraid not since AFAIK, the optical drive on the ThinkPad T540p is fixed, not user-removable like the older models that adopts the Ultrabay technology.

No the T400 is a much bigger laptop. Maybe this one? http://www.amazon.com/Lenovo-ThinkPad-Mini-Dock-Replicator-250410U/dp/B000BYA5NC/ref=sr_1_1?ie=UTF8&qid=1402411776&sr=8-1&keywords=lenovo+t400+dock

Yes. I'm actually typing this on a docked t430.http://support.lenovo.com/en_US/detail.page?LegacyDocID=MIGR-72871

Yes. I was using a T410 with the same 10.8V battery and am now using this larger battery with 11.1V. (T430 is a slightly newer model but it shares most componemts with the T410.)

This model comes with 4 gb of removable ram, but nothing soldered onto the motherboard. If you go to crucial.com and plug in this model, it will tell you that the max capacity is 12 gb, which seems to indicate that there might be 2 gb soldered onto the motherboard, however this isn't the case with the T440. The best you can do is get an 8 gb stick and switch it in for the 4 gb.

No, the T440S uses a different dock. According to Lenovo, the correct dock for the T440S is part number 40A10090US.

Not sure - but I had tried one that was thicker, and that did not fit my computer - this one is quite thin. So at the time (2012) there were two types that were around. This (thinner) one fits the T430s for sure. (That is what I have). So if you search around and if the 440p uses similar parts to the 430s or is very similar form factor, then suggest there is good chance. It was very useful - I needed the extra hard drive space. Note that you even have to be careful about the 2.5" hard drives - there are two thicknesses (at least in 2012). The bay will fit pretty much any normal 2.5" harddrive, even one that isn't ultra thin enough to go 'inside' the laptop in its own harddrive caddy.

I had a Thinkpad T420 and it worked with that. If you want to be sure, go to the Lenmar website and ask. I asked them before I got my current laptop and they answered pretty quickly. As for how long it lasts? On the Thinkpad it would power it for about 2 hours.

Worked fine in my Lenovo t530 laptop. But you can check crucial.com for compatibility.

The 1.8 inch dimensions is critical, yes. Your laptop must also have the Micro Serial ATA plug, it's 16 pins and less than a half inch across. The t410 lists "250GB, 7200 rpm, MicroSATA Generation 2 interface" as a standard drive, so it looks like it has the right interface. Here's a link to the service manual: http://download.lenovo.com/ibmdl/pub/pc/pccbbs/mobiles_pdf/t410_t410i_hmm_en_63y0535_06.pdf - happy upgrading!

Mine is T420i so it will work. I looked up through the Lenovo website for the battery model before the purchase. You can do the same to make sure.
